As we all see that both aerosol cans and spray cans need to be processed by Necking Machine, so why do they?
First of all, because the things in the aerosol cans will be heated at constant and ordinary temperature, their top will be placed unstable. So the aerosol can needs necking.
Secondly, the necking process can protect the head of aerosol can.
Next, the necking of the aerosol can strengthens the edges and enhances the protection.
At the same time, the cans are more standardized after necking and they can easily overlap each other.
Finally, the necking of the aerosol can itself is also an art design.
Necking Machine is a significant equipment in Aluminum Aerosol Cans Line.
